I've been trying to unlock my Rogers Arc's bootloader for a while now and it doesn't seem to be working. I've flashed WWE firmware that wasn't Rogers branded and I still can't get into fastboot mode. Is there any other way of unlocking the Rogers Arc's bootloader?
By definition, Rogers branded phones can't have unlocked bootloaders (as I posted in the other thread, blagus is trying to work around this)
Just want to add that SIM-unlocking your phone won't make a difference either. I thought doing so along with un-branding it would allow me to unlock the bootloader, but I was wrong.

Wish it were true, but it's also bad logic.
SIM/network unlocking is independent of any software/firmware/bootloader.
The bootloader is loaded before any firmware/ROM (i.e. generic/debranded) meaning that altering anything on top of it wouldn't have an affect.
Right now, there's almost no reason to unlock the bootloader anyways. There are no custom ROMs available yet so the only reason would be to root 2.3.3 which can't be rooted with Gingerbreak.
Maybe this can help you? I haven't tried yet, but will do soon.

Hi guys,
I have Xperia Arc which was locked to 3 UK. I flashed generic firmware from http://forum.xda-developers.com/showthread.php?t=1115542 , rooted it and updated to 2.3.3 The phone is rooted and unbranded now, but it is still locked to the network. If I put another sim card it asks for Sim network unlock PIN. How can I unlock it?
Thanks
Im on 3 and UK there is no way to unlock it except from a code mate. I pm'ed u

There must be a way around this, it is software issue, I thought the lock was in firmware, but if not, where can it be? is it in bootloader? Or I flashed wrong firmware?

Now I'm really intrigued, why is it not possible? Can anyone explain this?
If XDA wizards have access to firmware source, why they can't remove this lock from there?
Or I know for sure that unlocked smartphones exist, why not to take firmware from them?
This is not a hardware feature (or is it?), so it should be possible to overcome this, am I wrong?
SIM/network locking has nothing to do with firmware/software, hence you can flash any firmware onto any phone and maintain your (un)lock.
It's a lower-level software lock on the radio which is loaded before any firmware.
Think BIOS password on a PC. It locks the PC regardless of what operating system you have on it and is loaded before any OS.
Carrier-branded phones also cannot be bootloader unlocked at the moment, but there aren't any custom ROMs yet so it's not a big issue.
@BluechipJ
Thanks for reply,
Do you mean this is done in the bootloader? I know it is possible to unlock bootloader.
And what do you mean by carrier-branded phones? this phone doesn't have any logos on it. There was carrier splashscreen and a couple of apps but they are gone now after I flashed generic firmware. Is my phone still branded or not?
It is not branded but sim-locked now.

No, the radio/network/SIM lock is separate and independent from the bootloader and any firmware.
Carrier-branded means the phone had carrier apps/logo/is sold directly by the carrier. My Rogers arc does not have any physical logos either. It had Rogers applications and splash but like yours, are now gone since I flashed a generic firmware. However, it is still a carrier-branded phone. It was sold directly by a carrier. The bootloader is therefore, locked and cannot be unlocked (yet).
You can go to the Sony Ericsson site (http://unlockbootloader.sonyericsson.com/) and get your unlock key, but there is no way to get into Fastboot mode to enter it (on carrier-issued phones).

I just thought the other brand(s) of android phones is not as secure as this, that we need to pay for an unlock code. Others can just be sim-unlocked by software!
You can unlock the Phone using the Unlock code,You can get the Unlock code from the site www.theunlockspot.com and unlock it..Then you can use in any Country GSM Carriers.
No! It is possible to unlock the phone with proper simlock.ta cuz I have locked it by flashing it. God damn it!
So it is possible to vice versa.

So, Did you have success???
I have just rooted my phone. I wonder if I can unlock bootloader after rooting?
If I can, which way is the easiest way?
And also I want to know the benefits of unlocking Bootloader.
I want to add that I don't know so much about doing so complicated things, please know that while informing me.
I really appriciate your answers...
stock rom Gingerbread 2.3.3, rooted.
Rooting and bootloader unlocking are separate. Your bootloader has to be unlocked using a special code unique to your phone. The code is supplied by Sony Ericsson. It won't work if your phone is a carrier locked one. Unlocking the sim card won't enable it either. You need something called fastboot and only unbranded, unlocked phones have it.

Not sure exactly where to post this as your forums are very American Carrier focused so I just went with model number.
I am just entering the world of rooting Android phones etc. so forgive my noob-osity but am eager to learn after realising this carrier phone really isn't MY phone.
I am wanting to use Chainfire's CF-AutoRoot to get root access on my Australian Vodafone GT-N7105T device however his instructions make very clear that the device will be bricked if I do not unlock the bootloader. I cannot seem to find a method of unlocking the bootloader for this specific device. Can anyone help with this?
Also just in general, some Rooting methods I have read about don't seem to "require" unlocking the bootloader or maybe haven't mentioned that it is part of the process.
Is unlocking the bootloader something that needs to be done ALWAYS when you root? I thought that unlocking the bootloader was only required if you wanted to flash custom ROMs and that having a locked bootloader did not prevent some rooting methods? If that is the case then I'm confused as to why Chainfire's CF-AutoRoot needs an unlocked bootloader as it's purpose is to leave everything stock?
Thanks for your assistance.
I'm not the only semi-noob out here. I'm sure not many of us fully understand the consequences of having an XZL that won't let you unlock the bootloader. So...
If you cannot unlock your bootloader, what are the ramifications? Will the number of available custom roms be fewer? Can we have no custom roms at all?
Also, how can you ensure that you get an unlockable phone. I'm in canada, if I order the XZL through Bell, am I 100% certain to get a phone that wont let you unlock the bootloader? Do I have to buy the full thing off contract if i want an unlockable bootloader?

even if you buy the phone from bell off contract the bootloader will still be locked
i live in toronto and ordered the zl online and i already have unlocked my bootloader
as for roms there are some that can still work but yes it limits the customization that you can acheive with an unlocked bootloader

hi mate, just wonder whether you still have BE2 & Walkman after unlocking BL?
edit: got the answer.
I have an ATT phone currently unlocked and using it on T-Mobile. I want to root and use it on T-Mobile, but Im a little nervous that once I root, and wipe everything, the phone will be re-locked to ATT. So my question is, once I root will I lose my carrier un-lock?
It might be helpful to clarify a couple of things. It sounds like you're currently SIM-unlocked (thus able to use your AT&T branded M9 on T-Mobile). Are you currently bootloader-locked and want to unlock it so you can root? Or are you already bootloader unlocked?
Rooting definitely does not wipe/re-lock anything. Unlocking your bootloader triggers a system wipe. My understanding is that once your phone is SIM-unlocked, system wipes don't affect your phone's SIM status.
Sorry for the confusion. I am currently sim unlocked, and I want to bootloader unlock. However, before I unlock my bootloader, I want to make sure that I wont re lock my sim. My ultimate goal is to unlock bootloader in order to root, but I dont want to relock my carrier to ATT. Yes, it is an ATT phone and I'm using it on T-Mobile.
I'm pretty sure that unlocking the boot loader will not affect your SIM-unlocked status.
But if it were me, I would want a more definitive answer than that.
Another forum member may be able to answer for sure. In the meantime, consider asking HTC directly via their chat system. I've found them friendly and straightforward.

No you won't lose your unlocked network status.
The unlock once done is permanent.
There was one a while ago on the s3, an app, which was unofficial and I lost that a few times between flashes, but I don't think you'll have that issue.
Thank You. Unlocked boot loader, rooted and still have sim-unlock.
